6 Operation
6.1 Power up and system checkout
Switch main panel power to ON and then switch SPC’s branch circuit
breaker to ON. One LED should light for each phase voltage being
monitored. Single phase electrical systems will light only one LED,
split phase systems light two LEDs, and three phase systems will
light all three LEDs.
If the connected LEDs do not light, remove power, check connec-
tions, and test again. If the LEDs still do not light, contact your local
authorized distributor or Power Quality Technical Resource Center at:
the SPC may be damaged.
6.2 LED color states
The LED’s located on the lid of the SPC has three LED color states,
Green – fully protected
Yellow – loss of Neutral to Ground protection
Red – loss of phase protection
If the electrical system is single, split or 3 phase, the SPC will have
either one, two or three green illuminated LEDs, respectively. Each
LED will illuminate when its associated phase voltage is present.
If any of these LEDs are yellow or red a problem may exist with
incoming power, wiring, branch circuit breaker wiring or within the
SPC itself. Disconnect power, check connections and test again. If
the LEDs are still yellow or red, disconnect power to the SPC and
contact your local authorized distributor or Power Quality Technical
Resource Center at: 1-800-809-2772, Option 4, sub-option 2, or
6.3 Options: audible alarm and form C relay
ote:N Utilization of Form C contacts is optional. Connection is not required
for the proper operation of the SPC.
The audible alarm and Form C relay are tied to the Phase LED’s
located on the SPC Series enclosure’s lid. If protection to one or
more phases is lost the following will occur:
•
Single, Split and 3 Phase devices - if all voltage is lost to the SPC
then the green LED(s) will go out, the alarm will not sound and
the relay will not be energized.
•
Split and 3 Phase devices - if one phase voltage is lost to the SPC
then that one green LED will go out, the alarm will not sound and
the relay will stay energized (if there is another phase voltage
present).
•
3 Phase Wye and 3 Phase High Leg Delta devices - if one or two
phase voltages are lost to the SPC then one or two green LEDs
will go out, the alarm will not sound and the relay will stay ener-
gized (if there is another phase voltage present).
•
3 Phase Delta – SPC needs at least 2 phases to energize the relay
and to keep the alarm from sounding (if installed).
•
Single, Split and 3 Phase devices - if one or more LEDs turn red,
the alarm will sound and the relay will de-energize. To silence
the alarm, disconnect power to the SPC and contact your
local authorized distributor or Power Quality Technical Resource
Center at: 1-800-809-2772, Option 4, sub-option 2, or email
ote:N Form C relay contacts are “fail safe” and only change state when
power is applied to the SPC and the electrical system is operating normally or
when loss of protection is detected and yellow or red LEDs are illuminated.
